I was reading the literature as I usually do and found that it is actually well-documented that azithromycin (and probably other macrolides) actually inhibit biofilm formation. I even found a study that found azithromycin inhibited the formation of alginate, which is the main component of biofilms that Lyme itself makes (confirmed in many studies, especially Eva Sapi PHD's research). Azithromycin also inhibits bacterial quorem sensing - this is how bacteria communicate with each other, form biofilm colonies together, and so on.
Here are just two studies I found, but there are tons (you will need access to research database to read the full article):

Hoffmann, Nadine, et al. "Azithromycin blocks quorum sensing and alginate polymer formation and increases the sensitivity to serum and stationary-growth-phase killing of Pseudomonas aeruginosa and attenuates chronic P. aeruginosa lung infection in Cftr−/− mice."
